Terutoshi awakens a spirit when he kills a baby bird on the way to school. To right the wrong and fulfill its dream of growing up and bearing offspring, the spirit curses Terutoshi with a task: to impregnating another person. Branded with the spirit's seal, his best and only choice now is to fornicate with Ms. Sayumi, his teacher.

I'm Katy, luscious schoolgirl - attacked and left to die...But you, my Master, raped the life back into me, and made me into a Semen Witch!Shall I take it in my mouth or between my heavy breasts? Tell me what to do!Watch inside me as you force your way up into my womb!Listen to your little girl talking dirty as you stretch me and pump me, and make me pregnant ten times over!
